Wk ttr 50 injection engine Good runner Starts rides If u need postage I will drain oil Would recommend doing valve clearances it’s only done 3k miles One exhaust mount will need a longer bolt with a nut on the end the other is fine. Mount has been drilled out see pictures This engine is commonly used in other small bikes. This engine will fit carb engine if it’s same engine number But u will have to cheak stator and possibly change it to fit carb engine.
